11' Bibeau contractors dump?

I may be upgrading trucks and am looking for an 11' Bibeau contractors box. A used one that isn't beat too much would work also. If anyone knows of one, let me know. I have a picture of the old truck with the box.

I want the exact same box but much newer or hoping an Upfitter has one they would like to get rid of. I know of some 9' bodies but I need that extra two foot. I wish I could live with the shorter because they are cheap compared to the 11'. Worst case I will have to fix this one and reuse it.
